Definition of Relation. A relation is a set of ordered pairs. This seems like an odd definition but weâll need it for the definition of a function (which is the main topic of this section).
Classic (Swedish) massage and Thai massage have been proven to relieve chronic lower back pain. Classic massage for lower back pain is a technique that relaxes muscles in the area through the application of pressure. The area is rubbed in the direction in which blood flows back to the heart. Thai massage, on the other hand, is a technique that pulls and stretches the area of the back and neck.
For optimal results, ice massage therapy should be gently applied to the lower back as follows: 1  Apply the ice gently and massage in a circular motion. 2  Focus the ice massage therapy on the six-inch area of the back where the pain is felt.
